Dasui's Fire at the End of the Kalpa (BCR 29)

KOAN:

A student asked Dasui,
“It’s clear that the fire at the end of this kalpa will completely destroy the universe.

I’m still not clear whether there’s something that won’t be destroyed.”
Dasui said, “It will be destroyed.”

“It’ll leave along with everything else?”

“It will leave along with everything else,” said Dasui.
